Abstract This paper reports detailed propagation analyses of mm-wave indoor networks based numerical simulations of the wireless coverage and measurements of the propagation coefficient at 28 and 38 GHz. Additionally, ma...

Topicality of comparative study in Foreign Direct Investments (FDI) is determined by the need to deepen analysis of economic activity challenges and opportunities related to cross-border investments. Research in FDI tren...

PURPOSE: To develop and validate an automated computational tool for calculating a slice-specific volume computed tomography (CT) dose index (CTDIvol), a water-equivalent diameter (Dw), and size-specific dose estimates (...

Abstract Introduction Tobacco is one of the biggest public health problems and a major risk factor for various non-communicable diseases (NCDs). An important aspect of tobacco control strategy could include modifications...

Abstract The operation of a shield tunnel boring machine (TBM) in a high-strength hard rock stratum results in significant cutter damage, adversely affecting the thrust and torque of the cutter head. Therefore, it is ver...

Although the mobility protocols have improved, Proxy Mobile IPv6 (PMIPv6)-Based Distributed Mobility Management (DMM) networks still have significant challenges to ensure a seamless user mobility. These problems include ...

Abstract Currently, transplanting mechanisms for dryland plug seedlings in China are mainly semiautomatic and have low efficiency. The rotary seedling pick-up mechanism with a planetary gear train for non-uniform intermi...

Abstract A novel method was proposed to design the structure of a bone tissue engineering scaffold based on triply periodic minimal surface. In this method, reverse engineering software was used to reconstruct the surfac...

Abstract Three-dimensional (3D) printing technology is expected to solve the organ shortage problem. However, owing to the accuracy limitations, it is difficult for the current bioprinting technology to achieve an accura...

Abstract Background A national drug resistance survey (DRS) was implemented for the first time in Timor-Leste (TL) in 2019. The primary objective of the survey was to assess the prevalence of drug resistance among new an...

Abstract Introduction Fever is one of the most frequent reasons for paediatric consultations in Burkina Faso, but health care-seeking behaviours and the factors associated with health care-seeking in the event of childho...

Abstract Background Community-based health insurance (CBHI) schemes are crucial for households to avoid financial hardship, improve healthcare quality, and engage in health policies. Household satisfaction is a key indic...

Abstract Introduction The policy-making process in health reform is challenging due to the complexity of organizations, overlapping roles, and diversity of responsibilities. The present study aims to investigate and anal...

The global shift towards sustainable bioenergy demands not only improved biomass upgrading methods but also credible validation of their techno-economic and environmental feasibility at an industrial scale. Torrefaction ...

Abstract As electro-hydrostatic actuator (EHA) technology advances towards lightweight and integration, the demand for enhanced internal flow pathways in hydraulic valve blocks intensifies. However, owing to the constrai...

Abstract The processed surface contour shape is extracted with the finite element simulation software. The difference value of contour shape change is used as the parameters of balancing surface roughness to construct fi...

Abstract Solar arrays are the primary energy source for spacecraft. Although traditional rigid solar arrays improve power supply, the quality increases proportionally. Hence, it is difficult to satisfy the requirements o...

Abstract The friction judder characteristics during clutch engagement have a significant influence on the NVH of a driveline. In this research, the judder characteristics of automobile clutch friction materials and exper...

The purpose of this study is to examine the impact of green innovation products on an organization’s social performance through mediation of green supply chain management. Using stakeholder resource-based view theory a...

The performance of Photovoltaic (PV) power generation systems, using traditional Vector Current Controllers based on Proportional–Integral Action (CVC-PI), exhibits marked non-linearity and is strongly influenced by me...

Abstract Background It is imperative that researchers studying medical tourism connect their work with policy, so that its real-world challenges can be better understood, and more effectively addressed. This article gaug...
